Hi Maggi,
Thanks for reaching out to us, I am happy to help!
All of our drivers can be downloaded from https://plugable.com/drivers, select the product type from the table and you will be directed to the specific download page.
If you are unsure which download you need, let me know the model number ( normally on the bottom of the device ) and I will send you a direct link.
Thank you,
Pat
